Description

    BACKGROUND
  • Unit dose products provide convenience to consumers to be able to quickly and easily add a desired amount of product to laundry. One such product is fabric conditioner. To improve on fabric conditioners, it would be desirable to add encapsulated fragrances that can be delivered during the wash. A problem with encapsulated fragrances is that they are typically supplied in a suspension with more than 50 weight % water. This water creates instability in the water soluble pouch that contains the product. Also, there is a need to disperse fragrance capsules to obtain a more evenly distributed deposition of the fragrance capsules on fabric. Also, there is a need to disperse the fabric conditioner throughout the wash.
    EP 1 431 383 A1 discloses a unit dose fabric treatment product comprising a nonaqueous liquid fabric treatment composition contained in a single compartment watersoluble pouch.
    WO 2011/149475 A1 discloses a composition comprising an esterquat that is a quaternized reaction product of an alkanol amine and a fatty acid having a ratio of fatty acid to alkanol amine of 1.5 to 1.75, wherein 45 to 75% by weight of the fatty acids are saturated.
    US 2008/0076698 A1 discloses a fabric softening composition comprising a cationic or non-ionic softening compound, a water dispersible cross-linked cationic polymer, acrylamide, a difunctional vinyl addition monomer cross-linking agent, a non-confined fragrance oil, an effective amount of at least one fabric or skin beneficiating ingredient encapsulated within a first polymer material.
    US 5,525,245 discloses a clear fabric softener microemulsion composition comprising a combination of diester quaternary ammonium surfactants, diamido ammonium surfactants and selected organic solvents.
    • BRIEF SUMMARY
  • It has been found that a combination of a polyol, alkoxylated alcohol, and dispersing polymer allows for incorporation of encapsulated fragrance slurries into unit dose fabric conditioners to disperse the encapsulated fragrance and fabric conditioner active during laundering.

  • A method of laundering fabric with the unit dose fabric conditioner according to the present invention is defined in claim 14.
  • Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter.
